Abstract

The invention relates to a ventilation device (LG) for supplying one or more rooms or a part thereof with conditioned supply air (ZUL) in exchange with exhaust air (ABL), having at least one fan and an air-air heat exchanger (36), through which a supply incoming air flow (AUL, ZUL) and an exhaust air flow (ABL, FOL) for exchanging heat and/or moisture between the supply air (ZUL) and the exhaust air (ABL) are guided, and having a heat pump (1, 2, 3, 4) in which a heat carrier fluid (WTF1) is guided in a circuit through a compressor (1), a condenser (3), an expansion valve (2) and an evaporator (4). The ventilation device contains, in the supply air flow (AUL, ZUL) of the air-air heat exchanger (36), a heat carrier fluid-air heat exchanger (29), by means of which the supply air flow (AUL, ZUL) and a heat carrier fluid flow (WTF1; WTF2; WTF3) for exchanging heat between the supply air and the heat carrier fluid (WTF1; WTF2; WTF3) and/or for influencing the air humidity of the supply air are guided. The invention also relates to a method for operating the ventilation device (LG).
